March 10, 2011Interview With John Rogers, Founding Scientist of MC10
John Rogers is a materials scientist noted for his contributions to applied physics, particularly his leadership in developing flexible electronic devices. In contrast to traditional solid-state electronics, where components are fabricated on semiconductor wafers, researchers have recently discovered that a host of organic (i.e., carbon-based) molecules can also act as semiconductors. In an early line of research, Rogers used microlithographic stamping technology to design high-density, complex circuits that could be fabricated on a flexible substrate similar to paper. He has raised the performance of such circuits substantially, to the point that they are finding their way into devices with modest speed requirements, such as commercial display technologies. Nevertheless, the capacity of known organic semiconductors to perform high-speed computations remains limited. To address this, Rogers has also devoted significant effort to developing flexible semiconducting films, based on silicon or carbon nanotubes, literally to stretch the boundaries of signal processing capacity on flexible substrates. Such devices can be placed in locations where standard silicon wafer technologies are impractical or impossible; the myriad of potential applications include photovoltaic cells, adaptive optics, electronic textiles, and implantable biomimetic circuits. Through his basic research in nanotechnology, chemical engineering, and applied physics, Rogers is building the foundation for a revolution in manufacture of industrial, consumer, and biocompatible electronics.
